The E55 is faster than the E46 M3. At the beginning you pull ahead of the E55, but when the E55 picks up speed, it will blow past the M3. I have raced many E55's and it is the same story....i have always lost.

With the new M3, it may be closer, but I still think the E55 is faster.

Please note that I am talking about E55 being faster on the street...not the racetrack.

smoke one last night driving home, dropped it to 3rd going about 80, once i hit 8300 or so, we we neck to neck, kicked it to fourth, still neck to neck, but once i was at about 120, the Machine 3 started to pull away, it was nice!!!! this is a sick vehicle!!!

...In my fathers clk55 i ran against one and beat him... Id like to think my new m3 could take my fathers clk55.

some of the CLK55's do not have the kompressor ... is this the 4 pipe CLK55??? ... i raced a 2 pipe non kompressor CLK55 cabrio against my 335i cabrio and murdered him, it would have been a different story on the highway if it was the kompressor version.

my runs with my E46 M3 against a E55, off a line the M3 is quicker but after some time around the 140-160km/h (what i can recall) mark the E55 comes for you, and boy does it come for you verrrrrry quickly ... the other day my friend with his m3 cabrio E46 ran against an E55 from the line, that was murder by the E55 from the line, that car is quick, the poor m3 cabrio stood no chance what so ever .... so i still think the E55 will be quicker on a quarter mile sprint, BUT thats all an E55 is good for ... a straight line, in fact all AMG mercs! ...

wow i gotta see that to believe that....

in reality guys the e92 m3 is not that fast...

it is not like the e46... the e46 m3 came out in 01 and murdered everything in its time around a track and drag...

i am really disappointed with the new m3's performance but you can argue against its styling

without a doubt we need new CSL , new M3 is bigger and heavier now, it doesnt stand a chance against AMGs and their huge tourqe..I was watching a drag race between new 7 Alpina and CLK 63 AMG Black Series , The 7 got the jump on the clk but later clk was faster in straight line , also M3 CSL vs SL 55 AMG...guess what , the SL lost pretty good..
M3 = heavy car , needs more than 420hp and the answer is CSL , I hope this arrives soon

The one thing all AMG's have is HUGE torque....more HP doesn't hurt either..... they rated the CLS55-E55 at between 469-493hp....so they clearely have more HP....516 ftlb or torque is almost double the M3 too..... I would be afraid of any 55 AMG in a straight line.....add curves and braking.... I'm not worried at all!!
